I am very, very impressed of that price. I thought It would be much more north of 1.500 USD/EUR. Although I still like to wait for some "independent" sample pics and some reviews of sources I can sort out better, I'll be with CRs take.

Some people seem very quick to write this lens off but I'll wait until more reviews and hands on. I was considering the 100-400 Canon before I heard about this lens. Honestly, if this lens can outresolve the Canon at the 200-400 length and have decent sharpness at the 500-600 focal lengths I am sold. Of course, the AF speed should be at least on par with the Canon if not better. If that is all in then I will buy one in a heartbeat. I am not a pro but just need a super tele for the rare times I shoot wildlife or sports.

Hi Frank, that's cool you translated it this way, and I respect that you admit it, too! I've been brought up internationally (lived abroad, attended international schools) and I love the diversity of people who attend this forum. It's just great

=D actually there are more detail in english version which i cannot wrote correctly in chinese .__.i know the english phrase but no aviliable Chinese phrase . watch too much streaming and play with NA server people made me wrote a english article easier than made a chinese one although the grammar and english fail sometimes like "i am impressive with this lens " YOLO~

oh seems similar to what i expected and memories when i try out the big canon prime cannon(dat price and size , g8 bokeh and sharpness , i only able to hand held and use about 15-20 second before my hands shaky)

and the test show that 2x TC was really a bad choice and use it while aren't any better option. i found that crop without 2x is better than pics with 2x on my 70 200 2.8 II , expected result on 300 2.8 with 2X ,greatly chop down the contrast and sharpness .

i asked certain of people and meet next week to compare it towards canon 100 400 / bigma , not sure can we found a 200 400 1.4 tx but we gonna try hard. sony did not like tamron having VC on the lens , i need a lens with vc to using with e mount NEX / A7 . while no IBIS and with that LA -EA , lens VC are important =[

I've never heard that one before! It's amazing and funny! good one Frank

credit giving to the original : "my wallet is like an onion. when i open it i cry" <you can this series of photo at google searchi collect certain of meme and using in my facebook =D

but i doing in my way cause it was hard to memorize all of them.we knew that expensive lens are good just like flag ship cars , but most selling are in lower price tag lens .btw it was strange that anyone will get a flagship smartphone ~"~ they like to spend like 700 USD for a flaghip samsung but not a DSLR + LENS ,weird

for some situation i prefer smaller cmos/frame size like APS, 4/3 or even smartphone . just because i dont need to stop down too many to get enough DOF , for smartphone they are 5mm , F2 , act as a 24mm. for that 2.5 mm aperature (DOF) i need to like F10 on 24mm on a fullframe . i've been too painful for shooting small object and Miniatures , before i knew how does the DOF work (trade off accepted by using smartphone)

1) The VC. People keep saying it doesn't work that well, but the VC I tried in the 18-270 did. I routinely use mode 1 (2 axis) in panning situations when shooting airplanes at airshows so that I can use slower shutter speeds to preserve prop blur. I'd love to hear more about how well the VC works both on stationary subjects and while panning. I currently use the 70-200/2.8L IS II and 2x TC III, which has outstanding stabilization.

2) The F!@#$%N zoom ring rotates in the wrong direction. Everyone does this wrong (Tamron, Nikon, Sigma) and Canon does it right. I'm not sure I could get used to switching back and forth between this one and my Canon zooms.

Actually Sigma goes either way, depending on the lens, sample from their website:

I've used zooms from different manufacturers and have gotten used to switching back and forth on the zoom direction, just like each lens is different ergonomically.
